1. There are 78 sophomores at a school. Each is required to take at least one year of either chemistry or physics, but they may
SVETLANKA909090 [29]

We are given that there are a total of 78 students. If we set the following variables:

\begin{gathered} C=\text{students only in chemestry} \\ P=\text{students only in physics} \\ PC=\text{students in physics and chemistry} \end{gathered}

Then, the sum of all of these must be 78, that is:

C+P+PC=78

Since there are 15 in chemistry and physics and 47 in chemistry, we may replace that into the equation and we get:

47+P+15=78

Simplifying:

62+P=78

Now we solve for P by subtracting 62 on both sides:

\begin{gathered} 62-62+P=78-62 \\ P=16 \end{gathered}

Therefore, there are 16 students in physics

Natalka [10]

Answer: 3x^4 +x^3 -2x^2 +3x +2

Step-by-step explanation:

(3x^4 - 2x^3 + 4x -2) + (3x^3 - 2x^2 - x +4)

There are no like terms for 3x^4, so leave it alone.

-2x^3 + 3x^3 = 1x^3

No like terms for -2x^2

4x - x = 3x

-2 + 4 = 2

Answer? 3x^4 +x^3 -2x^2 +3x +2

(Please mark brainliest! :) )
